18. Severity classification (if there is more than 1 possible classification


19. Provide supplemental information here

O - Unclassifiable/unassessable Would more expect twitching localized at application site than at ear after topical product application. Ear redness is not expected and may have numerous other potential causes. Being uncomfortable is unspecific and may have numerous other potential causes in a dog. Even though more expected after oral uptake, permethrin has the potential to cause slight neurological disorders in particular susceptible animals; however sensitive to touch is not expected. Ear secretion and further diagnosed bacteria and yeast in the ear are not expected after product application as inconsistent with pharmaco-toxicological profile of the product. Other causes should be considered. Though time to onset is consistent for initial reported signs, considering long time to onset for later reported signs (5 days), a product connection is unassessable.
